The idea is to keep the aux tank as an aux tank, so I can fill it only when I need to fill it for longer trips.
Aux tank is internal. Since I don't use it unless I go on long road trips, it just sits there and takes up the room inside
the rear of the vehicle.(Not to mention that I'm not too comfortable having an LPG tank inside the car all the time )

I like either,
1)Remove the aux and fit it back when I need it or
2)Plumb the aux in a way so it can only be refilled on demand

Separate filler is too much hassle, I prefer a simpler solution.

I've opened the LPG plumbing lines way too many times.
It's quite safe, as long as I know what I'm doing.
All the accidents we hear were from guys mucking around with LPG system without having much of a clue.
